[Interest] Do I need to build Qt from the source to have an app compile in 32 bit?

[Nuno Santos]

Hi,

I wanted to build in 32 bit because someone was telling me that the app was crashing on a 32 bit snow leopard mac. 

I thought this was the problem, however, today, after sending a new build in 32 bit the problem remains. The crash log is below. Can someone understand exactly why is it crashing?

Regards,

Nuno
